CS 193P iPhone Application Development. Good news! Fall (2013-2014) quarter's lectures (based on iOS 7) are available on iTunesU. The website you are looking at ( was retired a couple of years ago, but evidently iTunesU folks still need it for demo code downloads, so we'll continue to post that stuff here.
Please do not repost from this website on other websites--these downloads are for the individual use of those of you watching the course on iTunesU. Enjoy! Mac OS X Developer Library.
